Challenge Problems

Push your limits with challenges.

Question 1

Design a cascading system with two common emitter amplifiers. Include a buffer in your schematic design. Explain how your chosen buffer specifications (input resistance and output capacitance) will mitigate the loading effect between the two amplifiers.

💡 Hint: Reflect on the principles of circuit isolation and impedance matching in your design choices.

Question 2

Calculate the cascading gain of two amplifiers with respective gains of 8 and 12, considering a loading effect that reduces the effective gain by 25%. Show your work.

💡 Hint: Remember to apply the loading factor as a decimal multiplier.
